EUD-2018086-00 Rev.3, SmartScanNG² User's Guide for Wayside Enclosure Components, 14 May 2021 7
1.0 Introduction
This section summarizes the purpose of this guide, describes the SmartScanNG² system, tells
how to comment on this guide, tells how to order more copies of this guide, and covers STC's
standard warranty. It also covers the cautions and disclaimers of which the customer should
be aware of.
1.1 Purpose of This Guide
The technical staff at Southern Technologies Corporation (STC) created the SmartScanNG²
defect detection system. It is designed to monitor moving trains and report certain conditions
detected on these trains. The SmartScanNG² system is modular and firmware-driven.
Hardware and firmware can be changed to meet the unique needs of a given railroad. Thus,
some of the components that make up a SmartScanNG² system differ from railroad to railroad.
This guide covers the portion of the SmartScanNG² system that is housed within the wayside
enclosure. It describes the functionality, installation, and operation of these components.
1.2 SmartScanNG² - Wayside Enclosure Components
In this guide, the structure that houses the SmartScanNG² is called the "wayside enclosure."
This structure, which comes in many shapes and sizes, can be any appropriate waterproof
enclosure located adjacent to the tracks. It goes by many other names, such as bungalow,
location case, apparatus housing, and equipment enclosure.
Attached to the inside of most wayside enclosures is:
• One SmartScanNG² detector per track
• One power subsystem per SmartScanNG² detector
Attached to the outside of most wayside enclosures is:
• One antenna per radio
• One shielded temperature probe per SmartScanNG² detector
1.3 Cautions
Contact with electrically active parts could result in sparks, burns, and electric shock. Because
of this, you should avoid all electrical hazards when installing, wiring, operating, and
maintaining the SmartScanNG² system. Failure to do so could result in damage to the
equipment or serious injury to you.

814 May 2021, SmartScanNG² User's Guide for Wayside Enclosure Components, EUD-2018086-00 Rev.3
In operation, batteries generate and release flammable hydrogen gas, which, if ignited by a
burning cigarette, naked flame, or spark, may cause battery explosion with a dispersion of
casing fragments and corrosive liquid electrolyte. So, carefully follow the manufacturer's
instructions. Keep all sources of gas ignition away from the batteries and do not allow metallic
articles to contact the negative and positive terminals of a battery at the same time.
Do not install any tower, pole, mast, or antenna on a wet or windy day. Do not install them
near any type of power line. Be sure all parts of the system are out of falling range of any
overhead wires, including the lead to any building. Once installed, do not climb any tower,
pole, or mast. Failure to follow these instructions could result in injury or death.
1.4 Disclaimers
The correct use of this guide, the environmental conditions at the time of installation, the
method of installation itself, and the installation of customer-supplied components are beyond
the control of STC. So too are the correct use and maintenance of all or part of the
SmartScan system. Therefore, the installer, user, and maintainer must assume the risk of any
injury that might occur during installation, use, and maintenance of all or part of the SmartScan
system. STC assumes no risk, liability, or responsibility for errors and omissions on the part of
the installer, user, or maintainer.

1.7 Standard Warranty
Systems manufactured by Southern Technologies Corporation carry a 14-month warranty from
the date of shipment. Warranty is limited to repair or replacement at the sole discretion of
STC, of any goods found to be defective in either materials or workmanship during the 14-
month period following shipment. Warranty does not apply to a product with signs of obvious
abuse or a product that has been improperly installed.
STC warrants that goods represented by this warranty statement have been designed and
manufactured with all reasonable care and attention to appropriate regulatory documents.
STC makes no representation that the goods covered by this warranty are suitable for the
application they are used for. Application of the goods is at the sole discretion of the
purchaser.
Purchaser is responsible for shipment of the defective product to STC. STC will pay the return
shipping charges.
Products purchased from other vendors but included in STC systems carry the original
manufacturer's warranty, typically 12 months. Warranty claims for these products must be
made directly to the original equipment manufacturer.
